[0018] The utility model will be described in detail below with reference to the accompanying drawings.

[0019] Embodiment 1:

[0020] The following is combined with Figure 1-3The present embodiment is described as a fully automatic high-speed rotary tablet press, comprising: a pressing plate 1, the pressing plate 1 is controlled to rise and fall by a control system 2, a pressing rod 3 is connected to the lower surface of the pressing plate 1, a sliding sleeve 4 is slidably connected to the pressing rod 3, a hook piece 5 is connected to the lower surface of the sliding sleeve 4, a pressing die 6 is connected to the lower end of the pressing rod 3, the pressing die 6 cooperates with the die hole 7 to press the tablet, the die hole 7 is located on a fixed plate 8, each die hole 7 is provided with a hook groove 9, the hook piece 5 is slidably connected to the hook groove 9, and the ends of the hook pieces 5 all point to the outside of the circumference;

[0021] The control system 2 controls the pressing plate 1 to be lowered, and the pressing plate 1 drives the pressing rod 3, the pressing mold 6, the sliding sleeve 4, and the hook piece 5 to be lowered. When the hook piece 5 is completely placed in the hook groove 9, it stops descending and injects powder into the die hole 7. The lower pressing plate 1 is continued to be controlled to descend, and the sliding sleeve 4 slides upward along the pressing rod 3. The pressing mold 6 cooperates with the die hole 7 to press the powder into tablets. Since the hook piece 5 is completely hidden in the hook groove 9, no marks will be left on the surface of the tablet. After completion, the lower pressing plate 1 is lifted, and the lower pressing plate 1 drives the hook piece 5 to rise. The bottom of the hook piece 5 hooks up the tablet and discharges it from the die hole 7, and then slides to the outside of the circumference along the inclined surface of the hook piece 5, completing a fully automatic pressing.

[0022] The control system 2 includes a ball groove 21, which is opened on the upper surface of the pressure plate 1, a ball head 22 is slidably connected in the ball groove 21, the ball head 22 is connected to the telescopic end of the hydraulic cylinder 23, the fixed end of the hydraulic cylinder 23 is connected to the upper bracket 25, the lower surface of the upper bracket 25 is connected to a servo motor 26, the shaft end of the servo motor 26 is slidably connected in the rail sleeve 24, the rail sleeve 24 is connected to the upper surface of the pressure plate 1, the lower surface of the upper bracket 25 is connected to a support column 27, the lower end of the support column 27 is connected to a lower bracket 28, and the lower bracket 28 is connected to the fixed plate 8;

[0023] The telescopic end of the hydraulic cylinder 23 drives the pressure plate 1 to rise and fall through the ball head 22 and the ball groove 21. The shaft end of the servo motor 26 drives the rail sleeve 24 to rotate. The rail sleeve 24 drives the pressure plate 1 to rotate a fixed angle, so that the hook 5 rotates to above the next die hole 7. During the rotation, the tablets are centrifuged and thrown out without residue. When the pressure plate 1 rotates, the ball head 22 slides in the ball groove 21. When the pressure plate 1 rises and falls, the shaft end of the servo motor 26 slides in the rail sleeve 24 without interference.

[0024] The number of support columns 27 is the same as the number of die holes 7 and their positions correspond. A discharge pipe 10 is connected inside the support column 27. The upper end of the discharge pipe 10 is connected to a hopper 11. All discharge pipes 10 are provided with electromagnetic valves that can be controlled simultaneously. The discharge end of the discharge pipe 10 points to the die hole 7.

[0025] The powder is injected into the hopper 11, and the solenoid valve is opened at the same time when discharging the material. The powder is injected into the die hole 7 through the discharge pipe 10 to complete the feeding.

[0026] The vertical portion of the hook 5 is wider than the inner diameter of the discharge pipe 10 and is located in the direction indicated by the discharge pipe 10 .

[0027] The vertical portion of the hook 5 guides the powder that has not entered the die hole 7 into the die hole 7 to avoid waste.
